See my combo in sig. My car runs HOT! I took it out for the first time, 30 mile drive and the car ran consitantly half way up the stock gauge or higher. I know I need an aftermarket gauge to get the correct reading, but while looking at it with the Tweecer I am around 240Â°.

My cooling system consists of 3 row aluminum rad, flex a lite fan with
s-blades and a full shroud, 180Â° t-stat. T-stat was checked by placing in boiling water and it opened up. Rad cap is new.

Engine has 60 miles on it, cometic head gaskets.

I cant believe it runs this hot, any suggestions? What are you guys using for cooling systems?

I run a 3 row radiator, stock 195* t-stat, underdrives, and a mark viii fan. My car runs solid 195-200 all day long. I am going to say that either your fan isn't pulling enough air through the radiator or your head gaskets were installed the wrong way(coolant passages toward the back).

My car ran a little hot before as well, but not quite that warm. It still will creep a little after driving on the highway on a hot day, then sitting in traffic for extended periods of time. As long as I stay moving, it hangs right around 195 degrees.

Does the car have underdrive pulleys? If so, put the stockers back on. Do you have a blanket over the turbine housing? Have you put header wrap on the down pipe? Cutting down on ambient heat helped me out a bit. One of the best cooling mods I've done was turning one of my buddies loose on my front bumper with a dremel tool.

I have not measured under hood temps yet. I just installed a trubo blanket as well as wraping the DP in hopes of it lowering the underhood temps.

Not sure if it will make a difference or not, but I also just installed a Spyder intake. THe Spyder has a coolant crossover on the back passage between the heads. The Typhoon did not. Maybe this will help flow?

I am running the stock pullies. What areas of the front bumper did you guys cut away?

So did the burping not work or did you just not try it yet. Also, what are you using to control your fan? I was using one of the flex a lite controllers that has the probe in the upper radiator hose and it sucked. I finally said screw it and bought a DC control setup and I have never had a problem since.

The mark VIII fan I put in my notch is really working well. 180 degree thermostat. As soon as the fan comes on, you see the needle start dropping fast. It stays in the lower 1/4 of the gauge. The only thing with the mark fan is you need to add a 3G alternator, bigger wiring to support that alternator, a 75 amp relay for the fan and a controller of some sort. Then you need to trim the shroud and make a bracket to get it to fit. Not complaining but that is the reality of that fan. Once you have it in, it is really something.

Thanks to all who gave me ideas. I tried burping the car and no help, so I said screw it and took the heads off the car to inspect the head gaskets, sure enough they were on backwards. Live and learn. Car is back together and runs 190-200 all the time!

I still cant believe I did that.

As far as fan control I am using my TwEECer to turn my fan on and off. Programmed temperatures, works great!

I did the same thing when I built my motor, the headgaskets almost went on backwards. Then at 11pm as we were about to torque down the heads, I decided to hop on here and do a search. Turned out we did have them on backwards and we had to take the heads back off and flip them. Sure a lot easier to do on an engine stand versus in the car.
